In FIG. 1, the area | region RA of the wing part in the longitudinal direction and the area | region RB of the flap part in a longitudinal direction are shown and shown. The flap part in this embodiment is an area | region extended in the width direction outer side than the main-body part 2, and extends back from the rear end part of a wing part. The rear end part of the wing part used as the front end part of the flap part 60 is a part located most width direction inner side between the wing part 43 and the flap part 60. As shown in FIG. The rear end portion of the flap portion 60 is a portion cut inward from the front and rear regions in the vicinity of the rear end portion of the absorbent article. The rear end part of the flap part in this embodiment corresponds with the rear end part of the 1st recessed part 71 mentioned later. The rear end portion of the flap portion 60 may coincide with the rear end portion of the absorbent article or may not coincide with the rear end portion of the absorbent article.

Moreover, the absorbent article 1 is provided with the side sheet 41 provided in the outer side of the absorber 30 in the width direction W. As shown in FIG. The main body part 2 is an area | region in which the absorber 30 was arrange | positioned in plan view, and is the area | region in which the surface sheet 10, the back sheet 20, and the absorber 30 were laminated | stacked.

The surface sheet 10 is a liquid permeable sheet which permeates liquids, such as a body fluid. The surface sheet 10 covers the surface of the absorber 30 at least. The surface sheet 10 is not particularly limited as long as it is a sheet-like material having a structure that transmits a liquid such as a nonwoven fabric, a woven fabric, a porous plastic sheet, and a mesh sheet. As a raw material of a woven fabric or a nonwoven fabric, any of natural fibers and chemical fibers can be used.

The back sheet 20 has a length substantially equal to the length of the front sheet 10. As the back sheet 20, a sheet in which a breathable resin film is bonded to a nonwoven fabric such as a laminate nonwoven fabric mainly composed of a polyethylene sheet, polypropylene, or the like, a breathable resin film, a span bond, or a span lace can be used. It is preferable that the back sheet 20 is made of a material having a degree of flexibility that does not cause discomfort during wearing. It is preferable that the back sheet 20 is liquid impermeable and moisture-permeable, for example, it can be comprised by the microporous sheet which carried out the extending | stretching process of melt-kneading an inorganic filler in olefin resins, such as polyethylene and a polypropylene.

The absorbent body 30 includes hydrophilic fibers and pulp. The absorber 30 is formed of a material capable of absorbing body fluids such as menstrual blood. The absorber 30 may be formed by laminating hydrophilic fibers or powder by an airlaid method, or may be an airlaid sheet obtained by molding a hydrophilic fiber or powder into a sheet shape by an airlaid method, or a tissue (for example, a unit weight of 15 g) / Pulverized pulp mixed with a superabsorbent polymer may be disposed on and surrounded by tissue.

The absorbent body 30 which concerns on this embodiment is comprised by surrounding the pulp which laminated | stacked the surface type pulp, synthetic pulp, etc. at about 10-300 g / m <2> of basis weights with the protective paper (not shown). The absorber 30 may be almost uniform in thickness across the entire surface, or may be non-uniform in thickness. The protective paper is for maintaining the shape of the pulp, and for example, crepe paper or tissue paper can be used.

The absorber 30 is a shape extending in the front-rear direction, and is about a step smaller than the back sheet 20. The length of the width direction W of the absorber 30 corresponds to the crotch space of an adult woman, and is 50-80 mm in general. The absorber 30 is adhered to the back sheet 20 by an adhesive such as hot melt. In addition, in this embodiment, the absorber 30 and the surface sheet 10 are adhere | attached with the hot melt adhesive agent.

The absorber 30 is provided so as to include at least the center of the excretory contact area that the wearer's excretory contact contacts. The center of the excretion contact area | region becomes a center of the longitudinal direction and the width direction of the area | region which a wearer's excrement contact contacts. For example, in the absorbent article having the wing portion, the center in the longitudinal direction of the wing portion is the center in the longitudinal direction of the excretory contact region. Moreover, in the absorbent article which does not have a wing part, the position with the shortest length dimension of the width direction of an absorber becomes a center of the longitudinal direction of an excretory contact area | region. In addition, the excretory contact area is included in an area in contact with the wearer's crotch part and is located at a distance between both legs of the wearer.

The side sheets 41 are disposed on both sides of the surface sheet 10. Like the surface sheet, the side sheet 41 is arrange | positioned rather than the absorber 30 at the skin contact surface side, and comprises a part of surface sheet in this invention. The side sheet 41 can be selected from the same material as the surface sheet 10. However, in order to prevent the acupuncture points from flowing over the side sheet 41 to the outside of the absorbent article 1, it is preferable to have hydrophobicity or water repellency. The side sheet 41 covers a part of the side edge of the absorber 30, the wing part 43, and the flap part 60.

The side sheet 41 which concerns on this embodiment is comprised by the air through nonwoven fabric. Air through nonwoven fabric is soft and feels good. When arrange | positioning a flap part along a body, mounting feeling can be improved more by improving the texture of a flap part.

In addition, in the wing part 43 and the flap part 60, the intermediate sheet 35 is provided between the side sheet 41 and the back sheet 20 (refer FIG. 3). The intermediate sheet 35 is made of an air through nonwoven fabric. The air through nonwoven fabric emits hot air to the nonwoven fabric and recovers its volume by penetrating the blown hot air, thereby providing a soft and soft touch. When arrange | positioning a flap part along a body, a mounting feeling can be improved more.

By providing the intermediate sheet 35, a thickness difference and a rigidity difference are formed at the boundary between the region where the intermediate sheet is disposed and the region where the intermediate sheet is not disposed. For example, the flap portion 60 is easily deformed from the end of the intermediate sheet.

The intermediate sheet 35 is intermittently joined at least with the side sheet 41 and the adhesive agent. The intermediate sheet according to the present embodiment is adhered to the front sheet 10 and the back sheet 20 through a hot melt adhesive disposed in a spiral shape. By intermittently joining the intermediate sheet 35 and the surface sheet 10 and the like, the intermediate sheet 35 can be moved relative to the surface sheet, thereby maintaining a smooth texture.

In the absorbent article 1, peripheral portions of the front sheet 10, the side sheet 41, and the back sheet 20 are joined to each other, and the absorber 30 is sealed inside. As a joining method of the front sheet 10 and the back sheet 20, it is possible to combine any one or multiple of heat embossing, an ultrasonic wave, or a hot melt adhesive agent.

In the back sheet 20, an adhesive part coated with an adhesive in a plurality of areas is provided on the surface in contact with the underwear (see Fig. 2). An adhesive part is provided in the back surface side of a main body part, it is provided in the center adhesive part 51 for fixing the absorbent article 1 to the crotch part of underwear, and it is provided in the back surface side of the wing part 43, and the crotch part is rolled up and a wing part ( It is provided on the back side of the flap part 60, and the flap adhesion part 53 for fixing in the state which opened the flap part with respect to the back length of underwear.

In the state before use, the adhesive contact | connects the peeling sheet which is not shown in figure. The release sheet prevents the adhesive from deteriorating before use. And a peeling sheet peels by a wearer at the time of use.

Moreover, in the absorbent article which does not have a peeling sheet, you may be comprised so that an adhesive may deteriorate before use by the packaging sheet which packages an absorbent article individually. When an adhesive agent and a packaging sheet contact, it is preferable to perform the process which enables peeling of an adhesive agent on the surface of a packaging sheet, without reducing the adhesive force of an adhesive agent.

In the absorbent article 1, the crimping part 80 which compressed the surface sheet 10 and the absorber 30 in the thickness direction is formed. Moreover, the crimping | compression-bonding part should just be formed by crimping | bonding the surface sheet 10 and the absorber 30 in the thickness direction T at least, and various structures can be employ | adopted. For example, it can be formed by press working or embossing, and the shape may be a lattice network or a honeycomb shape.

The flap part 60 is provided with the some narrow part in which the width direction length was shorter than the width direction length of the front-back area | region. The cutoff portion has a first cutout portion 61 positioned at the front side and a second cutout portion 62 positioned at the rear side.

The flap portion 60 is located behind the first flap portion 63 located at the front side of the first cut portion 61 and behind the first cut portion 61, and is located in front of the second cut portion 62. The 2nd flap part 64 and the 3rd flap part 65 located behind the 2nd narrow part 62 are shown.

The 1st flap part 63 is an area | region from the rear inner side edge part 43RI located behind to the 1st narrowing part 61 among the inner edge parts in the width direction of the wing part 43, and is the rear inner edge part 43R1. ) Extends outward in the width direction as it goes rearward. In the 1st flap part 63, the 1st largest width position (outer edge part) 63WM located in the outermost width direction is located in the width direction outer side than the 1st narrow part 61. As shown in FIG. The first maximum width position 63WM is located behind the center in the front-rear direction of the first flap portion 63.

The second flap portion 64 is an area from the first cut portion 61 to the second cut portion 62, which becomes the rear end of the first flap portion 63, and is rearward from the first cut portion 61. As it faces, it extends outward in the width direction. In the 2nd flap part 64, the 2nd largest width position (outer edge part) 64WM located in the width direction outer side is located in the width direction outer side rather than the 2nd narrow part 62. As shown in FIG. The second largest width position 64WM is located behind the center in the front-rear direction of the second flap portion 64.

The 3rd flap part 65 is an area | region from the 2nd cut part 62 used as the rear end of the 2nd flap part 64 to the back end part 60RI of the flap part, and is rearward from the 2nd cut part 62. As it faces, it extends outward in the width direction. In the 3rd flap part 65, the 3rd largest width position (outer edge part) 65WM located in the width direction outer side is located in the width direction outer side rather than the 2nd narrow part 62. As shown in FIG. The third largest width position 65WM is located behind the center in the front-rear direction of the third flap portion 65.

4 is a diagram schematically showing a state in which the absorbent article 1 is attached to the undergarment. FIG. 5 is a cross-sectional view taken along the line BB ′ shown in FIG. 4. The external force directed from the outside in the width direction due to the wearer's movement or the like acts on the region fitted into the wing portion 43 disposed in the vicinity of the groin.

The wing portion 43 is a portion to which a force is applied from the outside in the width direction to the inside when the wearer closes the leg. The flap part 60 is arrange | positioned behind the wing part 43, and when a force is applied from the width direction outer side to the inner side, a force is applied toward the back from the front side where the wing part 43 is located.

At this time, since the 1st narrow part 61 and the 2nd narrow part 62 are formed in the flap part 60, the flap part 60 is the 1st narrow part 61 and the 2nd narrow part 62 ) To the starting point to absorb the force from the front side. For example, the force exerted on the wing portion 43 side is absorbed by the first narrowing portion 61, and the force propagating behind the first narrowing portion 61 can be reduced. Therefore, it can suppress that the force from the front side propagates to the whole flap part, and can prevent wrinkles and kinks generate | occur | produce in the whole flap part.

Moreover, the largest width position of the 1st flap part 63, the 2nd flap part 64, and the 3rd flap part 65 is arrange | positioned behind the center in the longitudinal direction of each flap part. For example, if the maximum width position of each flap part is located in the front side, only the front part of the flap part may be bent locally, and it cannot absorb a force in the whole flap part.

However, when the maximum width position of each flap part is located behind the center in the front-back direction of each flap part, a force can be absorbed in the whole flap part, and it can suppress that wrinkles generate | occur | produce locally.

Moreover, a 2nd largest width position is located in the width direction outer side rather than a 1st largest width position, and a 3rd largest width position is located in the width direction outer side rather than a 2nd largest width position. That is, the maximum width position of the flap part located in the back is located in the width direction outer side rather than the maximum width position of the flap part located in the front. Therefore, the force propagating from the front side can be absorbed by the front flap portion, and then absorbed by the rear flap portion. That is, the force can be absorbed in stages. Moreover, since the width becomes wider as it goes back, it can arrange | position along underwear.

In the flap part 60, the recessed part 70 which becomes concave in the thickness direction T is formed. As for the recessed part 70, as shown in FIG. 3, the side sheet 41, the intermediate sheet 35, and the back sheet 20 which comprise a surface sheet are compressed in the thickness direction. The recess 70 is branched from the first recess 7l and the first recess 71 extending rearward from the rear inner end 43RI of the wing 43, and the first narrowed portion 61. ) 2nd recessed part 72 which reaches | attains), 3rd recessed part 73 which reaches | attained from 1st recessed part 71, and reaches 2nd narrow part 62, and 1st recessed part 71 It has a 4th recessed part 74 branched by and reaching the 3rd largest width position 65WM vicinity located in the width direction outer side of the 3rd flap part 65. As shown in FIG.

The recess is compressed in the thickness direction from the front sheet side toward the back sheet side. By compressing from the front sheet side toward the back sheet side to form the concave portion 70, it is possible to suppress the tearing of the back sheet made of a film when forming the concave portion. In this embodiment, it is compressed toward the back sheet side from the side sheet 41 side which comprises a surface sheet.

The 2nd recessed part 72, the 3rd recessed part 73, and the 4th recessed part 74 are comprised so that it may extend to the width direction outer side from the width direction inner side as it goes back. By forming the concave portion so as to extend from the inner side in the width direction to the outer side in the width direction toward the rear side, the concave portion follows the direction in which the force is applied, so that the concave portion becomes the starting point of folding and the flap portion is folded naturally. Therefore, the flap part 60 becomes easy to fit neither body nor underwear. Accordingly, disordered wrinkles are less likely to occur in the flap portion, deformation without discomfort can be achieved, and a fresh feeling of wearing can be obtained.

Moreover, the outer edge part in the width direction of the 3rd recessed part 73 is comprised so that it may be located in the 2nd narrowing part 62. As shown in FIG. According to such a structure, the force propagated through the 3rd recessed part 73 becomes easy to reach a 2nd narrow part, and it becomes easy to be folded from a 2nd narrow part 62 and a 3rd recessed part as a starting point.

In addition, the recessed part 70 is provided in the position which does not overlap with the flap adhesion part 53 in the thickness direction T as shown in FIG. By constructing the concave portion 70 and the flap bonding portion 53 so that they do not overlap, the flap portion is not folded due to the bonding point between the underwear and the flap portion, so that the flap portion does not affect the bonding position to the underwear. (60) can be folded. Therefore, the flap adhesion part 53 is prevented from peeling from an underwear, and it becomes easy to hold | maintain an adhesion position in the whole absorbent article 1.

Next, a part of the manufacturing method of the absorbent article 1 which concerns on 1st Embodiment is demonstrated. In addition, about the method which is not demonstrated, an existing method can be used. The manufacturing method of an absorbent article performs a surface sheet formation process as a 1st step. Next, as a 2nd step, a surface sheet bonding process is performed. Specifically, the surface sheet 10 and the side sheet 41 are adhered by, for example, heat welding.

As a third step, an absorber molding step is performed. Specifically, the absorbent body 30 is formed by molding the pulp serving as the material of the absorbent body by the forming drum. In addition, the order of the manufacturing process of the surface sheet of a 1st step and a 2nd step, and the absorber shaping | molding process of a 3rd step may be reverse order.

In a fourth step, the bonding step is performed. Specifically, a bonding step of joining the absorber molded in the third step and the surface sheet and side sheet joined in the second step is performed.

In a fifth step, a first crimping process is performed. Specifically, the absorber 30 and the surface sheet 10 are compressed in the thickness direction to form the crimping portion 80. In a sixth step, a back sheet bonding process is performed. Specifically, the absorber, the surface sheet and the like on which the crimping portion is formed are bonded to the back sheet.

As a seventh step, a second crimping step is performed. Specifically, the side sheet 41, the intermediate sheet 35 and the back sheet 20 are further compressed in the thickness direction to form the recesses 70. After the step, a process of applying the adhesive is provided. By the said process, the absorbent article which concerns on this embodiment can be manufactured.

The wing portion is a portion to which a force is applied from the outside in the width direction to the inside when the wearer pinches the leg. The flap portion is disposed behind the wing portion, and when a force is applied from the width direction outer side toward the width direction inner side, the force is applied from the front in which the wing portion is located to the rear side. At this time, the flap portion can absorb the force from the front side by deforming the cut portion to the starting point.

Since the force applied to the flap portion from the wing portion side is absorbed by the narrowing portion, the force propagating behind the narrowing portion can be reduced. Therefore, propagation of the force from the wing part side to the whole flap part can be suppressed, and generation | occurrence | production of a wrinkle and a twist in the whole flap part can be prevented.

Further, by forming the concave portion extending from the inner side in the width direction to the outer side in the width direction toward the rear side, the concave portion follows the direction in which the force is applied, so that the concave portion becomes a starting point of folding and the flap portion is folded naturally. Therefore, a flap part is easy to fit also with respect to a body and underwear. Accordingly, disordered wrinkles are less likely to occur in the flap portion, deformation without discomfort can be achieved, and a fresh feeling of wearing can be obtained.
